Abstract

The invention relates to a device for preventing vortex formation during the pouring of molten metal from metallurgical vessels with a bottom outlet, thereby making it possible to avoid the drawing in of strands of slag due to vortex formation. Although radially arranged mechanical obstacles in the vicinity of the entry to the outlet or a plug bar for preventing the entry of slag were already known, the invention provides a further arrangement, which makes it possible to a further substantial degree to suppress the occurrence of a vortex which draws in slag. For this purpose, a refractory bar with a displacement body widened above the outlet is provided in the region of the vortex and in proximity to the outlet, the displacement body having a diameter at least approximately twice as large as the entry to the outlet. It can, in particular, be provided with a height above the plane of the entry equal to the diameter of the outlet from the metallurgical vessel. The flow which forms prevents vortex formation even when the level of molten metal is very low.
